[0072] This disclosure is not exhaustive, but merely illustrative of some embodiments, and is not intended to limit the scope of protection of this disclosure. Unless otherwise specified, each step in a particular embodiment can be implemented as an independent embodiment, and the steps can be arbitrarily combined. For example, a solution after removing some steps in a particular embodiment can also be implemented as an independent embodiment, and the order of the steps in a particular embodiment can be arbitrarily interchanged. Furthermore, the optional implementation methods in a particular embodiment can be arbitrarily combined; moreover, the embodiments can be arbitrarily combined, for example, some or all steps of different embodiments can be arbitrarily combined, and a particular embodiment can be arbitrarily combined with the optional implementation methods of other embodiments.
[0073] In each of the disclosed embodiments, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions of the embodiments are consistent and can be referenced by each other. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.
[0074] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure.
[0075] In this disclosure, unless otherwise stated, elements expressed in the singular form, such as "a," "an," "the," "the aforementioned," "this," etc., can mean "one and only one," or "one or more," "at least one," etc. For example, when using articles such as "a," "an," "the," etc. in translation, the noun following the article can be understood as either a singular or a plural expression.
[0076] In the embodiments disclosed herein, "multiple" refers to two or more.
[0077] In some embodiments, the terms “at least one of”, “at least one of”, “at least one of”, “one or more”, “a plurality of”, “multiple”, etc., may be used interchangeably.
[0078] The descriptions in this disclosure, such as "at least one of A, B, C..." or "A and / or B and / or C...", include the case where any one of A, B, C... exists alone, as well as the case where any combination of any of A, B, C... exists alone. Each case can exist alone. For example, "at least one of A, B, C" includes the cases of A alone, B alone, C alone, A and B combination, A and C combination, B and C combination, and A and B and C combination. For example, A and / or B includes the cases of A alone, B alone, and A and B combination.
[0079] In some embodiments, the notation "in one case A, in another case B" or "in response to one case A, in response to another case B" may include the following technical solutions depending on the situation: A is executed regardless of B, i.e., A is executed in some embodiments; B is executed regardless of A, i.e., B is executed in some embodiments; A and B are selectively executed, i.e., A and B are selected for execution in some embodiments; A and B are both executed, i.e., A and B are executed in some embodiments. The same applies when there are more branches such as A, B, and C.
[0080] The prefixes "first," "second," etc., used in the embodiments of this disclosure are merely for distinguishing different descriptive objects and do not impose restrictions on the position, order, priority, quantity, or content of the descriptive objects. The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different. Similarly, if the object being described is "information", then "first information" and "second information" can be the same information or different information, and their content can be the same or different.
[0081] In some embodiments, “including A,” “containing A,” “for indicating A,” and “carrying A” can be interpreted as directly carrying A or indirectly indicating A.
[0082] In some embodiments, terms such as "time / frequency" and "time-frequency domain" refer to the time domain and / or frequency domain.
[0083] In some embodiments, the terms “in response to…”, “in response to determining…”, “in the case of…”, “when…”, “if…”, “if…”, etc., can be used interchangeably.
[0084] In some embodiments, the terms “greater than,” “greater than or equal to,” “not less than,” “more than,” “more than or equal to,” “not less than,” “higher than,” “higher than or equal to,” “not lower than,” and “above” can be used interchangeably, as can the terms “less than,” “less than or equal to,” “not greater than,” “less than,” “less than or equal to,” “not more than,” “lower than,” “lower than or equal to,” “not higher than,” and “below”.
[0085] In some embodiments, devices, etc., can be interpreted as physical or virtual, and their names are not limited to the names recorded in the embodiments. Terms such as “device”, “equipment”, “circuit”, “network element”, “node”, “function”, “unit”, “section”, “system”, “network”, “chip”, “chip system”, “entity”, and “subject” can be used interchangeably.
[0086] In some embodiments, "network" can be interpreted as devices included in a network (e.g., access network devices, core network devices, etc.).
[0087] In some embodiments, the terms "access network device (AN device)," "radio access network device (RAN device)," "base station (BS)," "radio base station," "fixed station," "node," "access point," "transmission point (TP)," "reception point (RP)," "transmission / reception point (TRP)," "panel," "antenna panel," "antenna array," "cell," "macro cell," "small cell," "femto cell," "pico cell," "sector," "cell group," "carrier," "component carrier," and "bandwidth part (BWP)" can be used interchangeably.

[0089] In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals. For example, embodiments of this disclosure can also be applied to structures where communication between access network devices, core network devices, or network devices and terminals is replaced by communication between multiple terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, the structure can also be configured such that the terminal has all or part of the functions of the access network device. Furthermore, terms such as "uplink" and "downlink" can be replaced with terms corresponding to communication between terminals (e.g., "sidelink"). For example, uplink channel, downlink channel, etc., can be replaced with sidelink channel, and uplink link, downlink, etc., can be replaced with sidelink link.
[0090] In some embodiments, the terminal may be replaced by an access network device, a core network device, or a network device. In this case, the access network device, core network device, or network device may also be configured to have all or some of the functions of the terminal.
[0091] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.
[0092] In some embodiments, data, information, etc., may be obtained with the user's consent.
[0093] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.
[0094] IoT-related technologies include MTC (Machine Type Communications), NB-IoT (Narrow Band IoT), and RedCap (Reduced Capability UE). MTC and NB-IoT significantly reduce the cost of IoT terminals by employing technologies such as low bandwidth, single antenna, reduced peak data rate, half-duplex operation, and reduced transmit power. eDRX (enhanced Discontinuous Reception) and PSM (Power Saving Mode) greatly reduce the power consumption of IoT terminals. Simultaneously, MTC and NB-IoT can support a large number of IoT terminals accessing the network, thus meeting the demand for massive connectivity. NB-IoT is a low-power wide-area network technology with key characteristics such as low cost, low power consumption, strong coverage, and massive connectivity. It is largely based on the non-backward-compatible E-UTRA, with a coverage target of MCL of 164dB, greatly enhancing indoor coverage and supporting a large number of low-throughput, low-latency-sensitive devices. NB-IoT supports three operating modes: in-band, standalone, and guardband. Both uplink and downlink RF bandwidths are 180kHz. Downlink uses OFDMA technology with a 15kHz subcarrier spacing, while uplink uses SC-FDMA technology. It supports both single-tone and multi-tone transmission. Enhanced versions of NB-IoT support a wealth of features, including multi-carrier support, positioning, multicast, wake-up signals, and fast small data transmission, and can coexist with LTE and NR systems.
[0095] eMTC is an enhanced version of LTE-M (LTE-Machine-to-Machine), an IoT technology evolved from LTE. It is also a low-cost, low-power wide-area network technology. Compared to NB-IoT, eMTC has slightly weaker coverage, targeting an MCL of 156dB, but it can support higher transmission rates, some mobility, and voice services. eMTC has 1.4MHz uplink and downlink RF bandwidth and can support a maximum peak rate of 1Mbps.
[0096] RedCap, short for Reduced Capability, is a new technology standard based on 5G NR. Simply put, RedCap is a lightweight version of 5G. The large-scale industrial wireless sensor network (IWSN) use cases described by 5G requirements include not only the very demanding URLLC services, but also relatively low-end applications requiring small device size, support for fully wireless transmission, and battery life of several years. These applications have higher requirements than LPWA (i.e., LTE-M / NB-IoT), but lower than URLCC and eMBB. Furthermore, smart city surveillance cameras and wearable device use cases such as smartwatches, electronic health-related devices, and medical monitoring equipment also have the characteristics of small device size, simplified functions, and the need to connect to the 5G radio access network and core network, urgently requiring the introduction of lower-cost, simplified 5G NR terminals. Therefore, 5G NR introduced the NR RedCap issue in Release 17, and all standardization is expected to be completed by mid-2022.
[0097] A-IoT is a novel Internet of Things (IoT) technology. Compared to traditional IoT technologies, a significant characteristic is the massive number of A-IoT terminals (A-IoT UEs, A-IoT devices, A-IoT Tags) in the network, enabling the inventory and monitoring of large-scale objects. A-IoT terminal devices can also be customized to meet different application needs, making A-IoT technology widely applicable and highly practical. Compared to NB-IoT terminals, A-IoT terminals have a simpler structure, lower hardware and maintenance costs, and the entire device may or may not include a power supply.
[0098] A-IoT devices can be categorized into Type 1, Type 2a, Type 2b, and Type 2c. Type 1 and 2a devices are passive, while Type 2b is an active device. Type 1 devices operate based on backscatter, exhibiting the lowest complexity and lowest power consumption. Type 2a devices support energy storage and operate based on backscatter; their complexity and power consumption are higher than Type 1 devices, offering some signal amplification while maintaining relatively low power consumption. Type 2b devices operate based on active transmission, possessing both signal amplification and active information transmission capabilities. Furthermore, Type 2c devices possess both active information transmission and backscatter capabilities. These devices can harvest energy from the environment to power normal uplink and downlink transmissions. Environmental energy includes natural energy such as solar, wind, and nuclear power, as well as artificial energy such as electromagnetic waves emitted by artificial devices.
[0099] Currently, two basic topology scenarios are supported. As shown in Figure 1A, Topology 1 involves a direct connection between the A-IoT base station (or reader) and the A-IoT terminal (A-IoT UE, A-IoT device, A-IoT Tag, device). As shown in Figure 1B, Topology 2 involves communication between the A-IoT device and the UE, with the UE acting as an intermediate node sending data to the network side.
[0100] For devices that use backscattering for uplink transmission, a continuous wave (CW) energy source (CW node) is required to provide the electromagnetic waves for reflection. The CW is typically of constant amplitude. The CW node can be a standalone node or a base station / intermediate node (e.g., a UE) communicating with the device. The frequency of the electromagnetic wave reflected by the device can be exactly the same as the CW frequency or it can have some offset. The magnitude of the offset depends on the device's hardware characteristics; the offset may be a fixed value, or if the device hardware supports it, it may support multiple fixed values, or it may be a dynamically adjustable value.
[0101] Information transmission in A-IoT technology can be referenced from RFID. Currently, RFID information and data include the following types:
[0102] Select: Includes Select and Challenge. The reader / writer can use the Select command to select one or more tags within its coverage area based on the data stored in the tags, and the Challenge command to query the encryption and authentication types of the tags. The reader / writer can then inventory or connect to the selected tags.
[0103] Inventory includes commands such as Query, QueryAdjus, QueryRep, ACK, and NAK. Readers can use these commands to identify tags. An inventory count begins with a Query command and ends with sending another Query command, or sending a Select or Challenge command. Sending a Query command requires association with one of four defined sessions (S0, S1, S2, and S3), and a single session can only support one inventory count. Multiple tags may respond during an inventory count. The reader will detect a single tag response and request the tag's EPC code.
[0104] Access includes commands such as Req_RN, Read, Write, Lock, Kill, Access, BlockWrite, BlockErase, BlockPermalock, Authenticate, ReadBuffer, SecureComm, AuthComm, KeyUpdate, Untraceable, FileOpen, FileList, FilePrivilege, FileSetup, and TagPrivilege. The reader / writer can perform operations on tags such as reading, writing, locking, and deactivating them. It can also perform security-related operations such as authentication, and file-related operations such as opening files stored in the tag. Access operations involve multiple commands, and a single reader / writer may only support access to one tag.
[0105] Based on the above types, this disclosure proposes a reader information transmission format as shown in Figure 1C. After receiving control information, the device may continue to receive data information sent by the reader. Before receiving data information, the device needs a certain preparation time, such as the decoding time for control information and the preparation time for receiving data. In the above scenario, control information and data information are sent continuously, and the reader as a whole confirms the time-frequency domain resources. How to ensure that the device has sufficient preparation time to receive data information after receiving R2D control information sent by the reader is a problem that needs to be solved.
[0106] Based on the information transmission format shown in Figure 1C, this disclosure proposes a communication method and device, communication system, communication equipment, and storage medium based on the Internet of Things. The communication resources are defined through network devices, and the communication resources are used to send control information and data information to a first type of terminal device, ensuring that there is sufficient time to receive data information after receiving control information.

[0135] Figure 2A is an interactive schematic diagram of a communication method provided in an embodiment of this disclosure. As shown in Figure 2A, this embodiment of the disclosure relates to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1D. The communication system includes a network device and at least one first-type terminal device. The interactive method may include the following steps:
[0136] Step 2101: The network device and one or more Type 1 terminal devices determine the communication resources.
[0137] In some embodiments, the network device may determine communication resources based on protocol predefined rules, identifying a first resource and a second resource, wherein the first resource is used to send control information and the second resource is used to send data information.
[0138] In some embodiments, the first type of terminal device may determine communication resources based on protocol predefinition, determining a first resource and a second resource, wherein the first resource is used to receive control information and the second resource is used to receive data information.
[0139] In some embodiments, the first resource and the second resource satisfy any one of the following: the time interval between a first time point of the first resource and a third time point of the second resource is greater than or equal to a first time interval, where the first time point is the first time domain unit of the first resource and the third time point is the first time domain unit of the second resource; the time interval between a second time point of the first resource and a fourth time point of the second resource is greater than or equal to the first time interval, where the second time point is the last time domain unit of the first resource and the fourth time point is the last time domain unit of the second resource; the time interval between a first time point of the first resource and a fourth time point of the second resource is greater than or equal to the first time interval; the time interval between a second time point of the first resource and a third time point of the second resource is greater than or equal to the first time interval.
[0140] In some embodiments, the first time point is the first time-domain unit of the first resource, the second time point is the last time-domain unit of the first resource, the third time point is the first time-domain unit of the second resource, and the fourth time point is the last time-domain unit of the second resource. Here, a time point is a time-domain unit in which information occupies a time-domain resource; the time-domain unit can be a relative time unit or an absolute time unit. For example, the time-domain unit can be a time-domain symbol in which information occupies a time-domain resource, or a wireless frame, or a millisecond, etc.
[0141] In some embodiments, the first type of terminal device determines the first time interval based on a predefined protocol; or based on device information of one or more first type of terminal devices; or by sending the first time interval to a network device.
[0142] In some embodiments, the network device determines the first time interval based on a predefined protocol; or based on device information of one or more first-type terminal devices; or by receiving the first time interval sent by one or more first-type terminal devices.
[0143] In some embodiments, each first type of terminal device can determine a first time interval based on a protocol predefined or its own device information. The first time interval determined by each first type of terminal device can be the same or different.
[0144] In some embodiments, the network device may determine the first time interval based on a predefined protocol, or it may determine the first time interval for sending control information and data information to each first type of terminal device based on the first time interval sent by each first type of terminal device, or the network device may determine the first time interval for sending control information and data information to one or more first type of terminal devices according to the first time interval sent by one of the multiple first type of terminal devices.
[0145] In some embodiments, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0146] For example, the first time interval is predefined by the protocol, or pre-stored in the device by the vendor, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0147] In some embodiments, the first resource and the second resource satisfy the condition that the time interval between the second time point of the first resource and the third time point of the second resource is greater than or equal to the first time interval.
[0148] For example, the time-domain resources occupied by control information and data information satisfy a first relationship. This first relationship can be that the time interval between a first time point of the time-domain resources occupied by control information and a second time point of the time-domain resources occupied by data information is not less than / greater than the first time interval. The first time point can be the last time-domain unit occupied by the control information, and the time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point could be the last time-domain symbol occupied by the control information, or the last radio frame, or the last millisecond, etc. The second time point is the first time-domain unit occupied by the data information, and the time-domain unit can be a relative time unit or an absolute time unit. The time interval between the first time point and the second time point is not less than / greater than the first time interval.
[0149] For example, as shown in Figure 6A, which illustrates the determination of communication resources, the last time domain symbol of the time domain resource symbol occupied by control information is its first time point, and the first time domain symbol of the time domain resource symbol occupied by data information is its second time point. The time interval between the two time points is not less than a first time interval, which is predefined by the protocol as 4 time domain symbols.
[0150] In some embodiments, the first resource and the second resource satisfy the following condition: the time interval between a first time point of the first resource and a third time point of the second resource is greater than or equal to a first time interval, the first time point is the first time domain unit of the first resource, and the third time point is the first time domain unit of the second resource.
[0151] For example, the time interval between the second time point of the time domain resource occupied by control information and the second time point of the time domain resource occupied by data information is not less than / greater than the first time interval. The second time point is the first time domain unit in which information occupies the time domain resource, and the time domain unit can be a relative time unit or an absolute time unit. For example, the second time point is the first time domain symbol in which information occupies the time domain resource, or the first radio frame, or the first millisecond, etc. The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, and the time units can be relative time units, such as: time domain symbol, sub-time slot, time slot, subframe, radio frame, etc., or they can be absolute time units, such as: hour, minute, second, millisecond, microsecond.
[0152] In some embodiments, the first resource and the second resource satisfy the following condition: the time interval between the second time point of the first resource and the fourth time point of the second resource is greater than or equal to the first time interval, the second time point is the last time domain unit of the first resource, and the fourth time point is the last time domain unit of the second resource.
[0153] For example, the time interval between the first time point of the time domain resource occupied by control information and the first time point of the time domain resource occupied by data information is not less than / greater than a first time interval. The first time point is the last time domain unit in which information occupies the time domain resource, and the time domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time domain symbol in which information occupies the time domain resource, or the last radio frame, or the last millisecond, etc. The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Further, the first time interval can be n time units, which can be relative time units, such as: time domain symbol, sub-time slot, time slot, subframe, radio frame, etc., or can be absolute time units, such as: hour, minute, second, millisecond, microsecond.
[0154] In some embodiments, the first resource and the second resource satisfy the condition that the time interval between a first time point of the first resource and a fourth time point of the second resource is greater than or equal to the first time interval.
[0155] For example, the time interval between the second time point of the time domain resource occupied by the control information and the first time point of the time domain resource occupied by the data information is not less than / greater than the first time interval. The first time point is the last time domain unit in which the information occupies the time domain resource, and the time domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time domain symbol in which the data information occupies the time domain resource, or the last radio frame, or the last millisecond, etc. The second time point is the first time domain unit in which the control information occupies the time domain resource, and the time domain unit can be a relative time unit or an absolute time unit. The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Further, the first time interval can be n time units, and the time units can be relative time units, such as: time domain symbol, sub-time slot, time slot, subframe, radio frame, etc., or can be absolute time units, such as: hour, minute, second, millisecond, microsecond.
[0156] Step 2102: The network device sends control information and data information to one or more Type 1 terminal devices.
[0157] In some embodiments, the network device uses a communication device to send control information and data information to one or more first-type terminal devices.
[0158] In some embodiments, the network device uses a first resource to send control information to one or more first-type terminal devices, and uses a second resource to send data information to one or more first-type terminal devices. The first and second resources are determined in step 2101.
[0159] In some embodiments, a first type of terminal device receives control information on a first resource and data information on a second resource.
[0160] In some embodiments, the network device uses a first resource to send control information to one or more first-type terminal devices; and uses a second resource to send data information to one or more first-type terminal devices after a first time interval following a first time point or a second time point of the first resource.
[0161] In some embodiments, a first type of terminal device receives control information on a first resource and receives data information on a second resource after a first time interval following a first time point or a second time point on the first resource.
[0162] In some embodiments, the first time interval may be the first time interval determined in step 2101, which will not be described again here.
[0163] For example, data information needs to be sent during the first time interval of the control information. Specifically, the reference time point for transmission is at least one of the following: the first time point of the time domain resource occupied by the control information, and the second time point of the time domain resource occupied by the control information. The first time point is the last time domain unit of the time domain resource occupied by the information, and the time domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time domain symbol of the time domain resource occupied by the information, or the last radio frame, or the last millisecond, etc. The second time point is the first time domain unit of the time domain resource occupied by the information, and the time domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the first time domain symbol of the time domain resource occupied by the information, or the first radio frame, or the first millisecond, etc. The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0164] For example, as shown in Figure 6B, which illustrates the time-domain resources for control and data information, the last time-domain symbol occupied by the control information serves as the reference time point. The data information needs to be sent after the first time interval. The first time interval consists of four time-domain symbols, and the number of time-domain symbols can be predefined by the protocol.
[0165] In some embodiments, the control information includes at least one of the following: selection information, used to instruct one or more first-type terminal devices; query information, used to query at least one of the following information of one or more first-type terminal devices: encryption type, authentication type, battery level, supported information reporting type, device type, identification information, and pre-stored access information; inventory information, used to trigger inventory start or inventory end, or used to indicate at least one of the following: inventory cycle, inventory time length, and inventory round number; feedback information, used to indicate whether the information sent by one or more first-type terminal devices to the network device has been successfully received by the network device; read information, used to trigger a read operation, the read operation including at least one of the following: reading pre-stored information in a preset area of one or more first-type terminal devices, and reading result information after one or more first-type terminal devices perform a preset action; write information, used to trigger a write operation, the write operation indicating at least one of the following: a preset area where the information to be written is written, and the information to be written; lock information, used to lock one or more functions of one or more first-type terminal devices; and deactivation information, used to instruct one or more first-type terminal devices to deactivate.
[0166] In some embodiments, selection information is used by a first type of terminal device to know the terminal device selected by the network device.
[0167] In some embodiments, when selection information is available, the query information is used to query the selected terminal device; when no selection information is available, the query information is used to query all terminal devices that received the first information. In other words, the query information may not include identification information; that is, when the first information includes both selection information and query information, the query information does not include identification information, and the query information is used to query the terminal device indicated by the selection information.
[0168] In some embodiments, selection information can be used simultaneously with pre-stored access information and inventory information.
[0169] For example, feedback information can be used to indicate to the terminal device whether D2R has been successfully received, that is, whether the information sent by the A-IoT terminal device to the A-IoT network device has been successfully received by the A-IoT network device.
[0170] For example, reading information can be used to trigger a read operation, which can be reading pre-stored information in a specified area of the device, or reading the result information after the device performs a certain action.
[0171] In some embodiments, the purpose of the written information is not limited. For example, if the device needs to process data, then the reader needs to send the content of the processed data to the device, and the written information may be written data information; or, if the reader needs to instruct the device to perform a certain operation periodically, then the written information may be written control information.
[0172] In some embodiments, the deactivation information may be an instruction for the first type of terminal device to hibernate / deactivate, or the deactivation information may be to disable the first type of terminal device.
[0173] In some embodiments, the data information includes at least one of the following: data information stored in one or more first-type terminal devices in a first storage mode; data information stored in one or more first-type terminal devices in a second storage mode; information to be written corresponding to a write operation; data information requested by one or more first-type terminal devices from a network device; and data information notified by the network device to one or more first-type terminal devices.
[0174] In some embodiments, the first storage method is to store the data in a cache, which can also be called temporary storage. Data stored temporarily may be lost in the event of a power outage. The second storage method is to store the data in memory, which can also be called permanent storage. Data will not be lost in the event of a power outage.
[0175] For example, an A-IoT network device sends control information and data information to an A-IoT terminal device, wherein the control information is sent through a first resource and the data information is sent through a second resource, and the first resource and the second resource have a first time interval. Control information can be at least one of the following information types: selection information, used to indicate one or more devices; whether the recipient of the first information includes one or more devices; query information, used to query at least one of the following: device encryption and authentication type, device power level, device supported information reporting type, device type, device ID information, and device pre-stored access information; disk storage information, triggering disk storage start or end, or indicating disk storage related information, such as period, time length, number of rounds, etc.; feedback information, indicating whether D2R has been successfully received; read information, triggering a read operation: reading pre-stored information in a specified area of the device, or reading the result information after the device performs a certain action; write information, triggering a write operation: indicating a specific area to be written, or indicating specific information to be written; lock information, locking one or more functions of the device; deactivation information, indicating that the device is deactivated.
[0176] For example, the data information can be at least one of the following information types: data information temporarily stored on the device; data information permanently stored on the device; specific information for write operations; data information that the device requests the reader to send; data information that the reader actively notifies the device.
[0177] In some embodiments, the first type of terminal device is capable of performing at least one of the following operations on the data information: temporary storage, permanent storage, or ignoring.
[0178] For example, a device can temporarily store data, or permanently store it, or ignore it.
[0179] In the above embodiments, the network device and the first type of terminal device determine the first resource and the second resource, as well as the first time interval, so as to transmit control information and data information through the first resource and the second resource respectively, so that the first type of terminal device can have sufficient time to receive data information after receiving control information, thus ensuring the transmission of information.
[0180] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

As shown in Figure 2B, this embodiment of the disclosure relates to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1D. The communication system includes a network device and at least one first-type terminal device. The interactive method may include the following steps:
[0182] Step 2201: The network device sends a first transport block to one or more first-type terminal devices.
[0183] In some embodiments, the first transport block includes control information, data information, and an intermediate code, with the intermediate code located between the control information and the data information.

[0187] In some embodiments, the inductor carries information, and the time domain length of the inductor is the time interval between the control information and the data information.
[0188] In some embodiments, the control information includes at least one of the following: selection information, used to instruct one or more first-type terminal devices; query information, used to query at least one of the following information of one or more first-type terminal devices: encryption type, authentication type, battery level, supported information reporting type, device type, identification information, and pre-stored access information; inventory information, used to trigger inventory start or inventory end, or used to indicate at least one of the following: inventory cycle, inventory time length, and inventory round number; feedback information, used to indicate whether the information sent by one or more first-type terminal devices to the network device has been successfully received by the network device; read information, used to trigger a read operation, the read operation including at least one of the following: reading pre-stored information in a preset area of one or more first-type terminal devices, and reading result information after one or more first-type terminal devices perform a preset action; write information, used to trigger a write operation, the write operation indicating at least one of the following: a preset area where the information to be written is written, and the information to be written; lock information, used to lock one or more functions of one or more first-type terminal devices; and deactivation information, used to instruct one or more first-type terminal devices to deactivate.
[0189] In some embodiments, selection information is used by a first type of terminal device to know the terminal device selected by the network device.
[0190] In some embodiments, when selection information is available, the query information is used to query the selected terminal device; when no selection information is available, the query information is used to query all terminal devices that received the first information. In other words, the query information may not include identification information; that is, when the first information includes both selection information and query information, the query information does not include identification information, and the query information is used to query the terminal device indicated by the selection information.
[0191] In some embodiments, selection information can be used simultaneously with pre-stored access information and inventory information.
[0192] For example, feedback information can be used to indicate to the terminal device whether D2R has been successfully received, that is, whether the information sent by the A-IoT terminal device to the A-IoT network device has been successfully received by the A-IoT network device.
[0193] For example, reading information can be used to trigger a read operation, which can be reading pre-stored information in a specified area of the device, or reading the result information after the device performs a certain action.
[0194] In some embodiments, the purpose of the written information is not limited. For example, if the device needs to process data, then the reader needs to send the content of the processed data to the device, and the written information may be written data information; or, if the reader needs to instruct the device to perform a certain operation periodically, then the written information may be written control information.
[0195] In some embodiments, the deactivation information may be an instruction for the first type of terminal device to hibernate / deactivate, or the deactivation information may be to disable the first type of terminal device.
[0196] In some embodiments, the data information includes at least one of the following: data information stored in one or more first-type terminal devices in a first storage mode; data information stored in one or more first-type terminal devices in a second storage mode; information to be written corresponding to a write operation; data information requested by one or more first-type terminal devices from a network device; and data information notified by the network device to one or more first-type terminal devices.
[0197] In some embodiments, the first storage method is to store the data in a cache, which can also be called temporary storage. Data stored temporarily may be lost in the event of a power outage. The second storage method is to store the data in memory, which can also be called permanent storage. Data will not be lost in the event of a power outage.
[0198] For example, an A-IoT network device sends control information and data information to an A-IoT terminal device. The control information is sent via a first resource, and the data information is sent via a second resource. There is a first time interval between the first and second resources. The control information can be at least one of the following information types: selection information, used to indicate one or more devices; whether the recipient of the first information is included in these one or more devices; query information, used to query at least one of the following: the device's encryption and authentication type, the device's battery level, the device's supported information reporting type, the device's type, the device's ID information, and the device's pre-stored access information; inventory information, triggering the start or end of inventory, or indicating inventory-related information, such as period, time length, number of rounds, etc.; feedback information, indicating whether D2R was successfully received; read information, triggering a read operation: reading pre-stored information in a specified area of the device, or reading the result information after the device performs a certain action; write information, triggering a write operation: indicating a specific area to be written, or indicating specific information to be written; lock information, locking one or more functions of the device; deactivation information, indicating that the device is deactivated.
[0199] For example, the data information can be at least one of the following information types: data information temporarily stored on the device; data information permanently stored on the device; specific information for write operations; data information that the device requests the reader to send; data information that the reader actively notifies the device.
[0200] Step 2202: The network device sends second information to one or more first-type terminal devices.
[0201] In some embodiments, the second information is used to indicate the time-domain length of the middle preamble.
[0202] For example, the intermediate code is located between the control information and the data information, and the time domain length of the intermediate code satisfies a second relationship, which can be not less than / greater than the first time interval.
[0203] In some embodiments, the second information may be based on a protocol predefined.
[0204] For example, the time domain length of the inductor can be predefined by the protocol or indicated by the reader to the device via control information.
[0205] In some embodiments, the time-domain length of the middle preamble is greater than or equal to the first time interval.
[0206] In some embodiments, the first time interval may be determined based on a predefined protocol, or it may be determined based on device information of one or more first-type terminal devices, or it may be determined by the first-type terminal device sending information to the network device.
[0207] In some embodiments, the first type of terminal device determines the first time interval based on a predefined protocol; or based on device information of one or more first type of terminal devices; or by sending the first time interval to a network device.
[0208] In some embodiments, the network device determines the first time interval based on a predefined protocol; or based on device information of one or more first-type terminal devices; or by receiving the first time interval sent by one or more first-type terminal devices.
[0209] In some embodiments, each first type of terminal device can determine a first time interval based on a protocol predefined or its own device information. The first time interval determined by each first type of terminal device can be the same or different.
[0210] In some embodiments, the network device may determine the first time interval based on a predefined protocol, or it may determine the first time interval for sending control information and data information to each first type of terminal device based on the first time interval sent by each first type of terminal device, or the network device may determine the first time interval for sending control information and data information to one or more first type of terminal devices according to the first time interval sent by one of the multiple first type of terminal devices.
[0211] In some embodiments, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0212] For example, the first time interval is predefined by the protocol, or pre-stored in the device by the vendor, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0213] Step 2203: The first type of terminal device determines the second information.
[0214] In some embodiments, the first type of terminal device determines the time domain length of the intro code based on the second information sent by the receiving network device.
[0215] In some embodiments, the first type of terminal device may determine the second information, namely the time domain length of the intro code, based on a protocol predefined.
[0216] In some embodiments, the first type of terminal device determines the time-domain length between control information and data information, i.e., the time-domain length of the intermediate code, based on determined second information.
[0217] For example, the time domain length of the inductor can be predefined by the protocol or indicated by the reader to the device via control information.
[0218] In some embodiments, the first type of terminal device determines the length of the time domain resources occupied by the control information and the length of the time domain resources occupied by the data information in the first transport block by determining the time domain length of the intro code, so that there is sufficient time to receive the data information after receiving the control information.
[0219] In some embodiments, the first type of terminal device is capable of performing at least one of the following operations on the data information: temporary storage, permanent storage, or ignoring.
[0220] For example, a device can temporarily store data, or permanently store it, or ignore it.

Steps 2201+2202, 2202+2203, and 2201+2202+2203 may be implemented as standalone embodiments, but are not limited thereto.

[0273] The following are specific solutions provided by embodiments of this disclosure:
[0274] Example 1:
[0275] IoT network devices send control information and data information to IoT terminal devices. The time-domain resources occupied by the control information and data information satisfy a first relationship. The method for determining the first relationship includes at least one of the following:
[0276] Method 1: Protocol Definition
[0277] The time interval between the first time point of the time domain resources occupied by control information and the second time point of the time domain resources occupied by data information is not less than / greater than the first time interval.
[0278] The first time point is the last time-domain unit in which the information occupies time-domain resources. The time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time-domain symbol in which the information occupies time-domain resources, or the last radio frame, or the last millisecond, etc.
[0279] The second time point is the first time-domain unit in which the information occupies time-domain resources. This time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point could be the first time-domain symbol in which the information occupies time-domain resources, or the first radio frame, or the first millisecond, etc.
[0280] The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0281] For example, as shown in Figure 6A, which is a schematic diagram of the time-domain resources for control information and data information, the last time-domain symbol occupied by the control information is its first time point, and the first time-domain symbol occupied by the data information is its second time point. The time interval between the two time points is not less than a first time interval, which is predefined by the protocol as 4 time-domain symbols.
[0282] Method 2:
[0283] The time interval between the second time point of the time domain resources occupied by the control information and the second time point of the time domain resources occupied by the data information is not less than / greater than the first time interval.
[0284] The second time point is the first time-domain unit in which the information occupies time-domain resources. This time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point could be the first time-domain symbol in which the information occupies time-domain resources, or the first radio frame, or the first millisecond, etc.
[0285] The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0286] Method 3:
[0287] The time interval between the first time point of the time domain resources occupied by control information and the first time point of the time domain resources occupied by data information is not less than / greater than the first time interval.
[0288] The first time point is the last time-domain unit in which the information occupies time-domain resources. The time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time-domain symbol in which the information occupies time-domain resources, or the last radio frame, or the last millisecond, etc.
[0289] The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0290] Method 4:
[0291] The time interval between the second time point of the time domain resources occupied by the control information and the first time point of the time domain resources occupied by the data information is not less than / greater than the first time interval.
[0292] The first time point is the last time-domain unit in which the information occupies time-domain resources. The time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time-domain symbol in which the information occupies time-domain resources, or the last radio frame, or the last millisecond, etc.
[0293] The second time point is the first time-domain unit in which the information occupies time-domain resources. This time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point could be the first time-domain symbol in which the information occupies time-domain resources, or the first radio frame, or the first millisecond, etc.
[0294] The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0295] Method 5:
[0296] Data information needs to be sent after the first time interval of the control information. Specifically, the reference time point is at least one of the following: the first time point of the time domain resources occupied by the control information, and the second time point of the time domain resources occupied by the control information.
[0297] The first time point is the last time-domain unit in which the information occupies time-domain resources. The time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point is the last time-domain symbol in which the information occupies time-domain resources, or the last radio frame, or the last millisecond, etc.
[0298] The second time point is the first time-domain unit in which the information occupies time-domain resources. This time-domain unit can be a relative time unit or an absolute time unit. For example, the first time point could be the first time-domain symbol in which the information occupies time-domain resources, or the first radio frame, or the first millisecond, etc.
[0299] The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0300] As exemplified by the time-domain resource diagram of control information and data information shown in Figure 6B, the last time-domain symbol occupied by the control information is the reference time point, and the data information needs to be sent after the first time interval. The first time interval is 4 time-domain symbols, where 4 is predefined by the protocol.
[0301] Alternatively, the optional implementation of Embodiment 1 can be found in the optional implementation of the embodiment shown in Figure 2A.
[0302] Example 2:
[0303] The IoT network device sends a first transport block to the IoT terminal device. The first transport block includes: control information, data information, and an indicative code. Preferably, the time-domain length of the indicative code is predefined by the protocol. More preferably, the time-domain length of the indicative code is indicated by the control information.
[0304] Furthermore, the intermediate code is located between the control information and the data information, and the time-domain length of the intermediate code satisfies the second relationship. As shown in Figure 6C, which is a schematic diagram of the time-domain resources of the control information and the data information, the method for determining the second relationship is as follows:
[0305] The time domain length of the intermediate code is not less than or greater than the first time interval.
[0306] The first time interval is predefined by the protocol, or pre-stored in the device by the manufacturer, or reported by the device to the reader. Furthermore, the first time interval can be n time units, which can be relative time units, such as time domain symbols, sub-slots, time slots, subframes, radio frames, etc., or absolute time units, such as hours, minutes, seconds, milliseconds, microseconds.
[0307] Alternatively, alternative implementations of Embodiment 2 may refer to the alternative implementations in the embodiments shown in FIG2B.
[0308] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.
[0309] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
[0310] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0311] In this embodiment, the processor is a circuit with signal processing capabilities.
